How to Set Up a DayZ Standalone Server on Linux

This guide covers the installation of a DayZ server on a Linux machine (Ubuntu/Debian) using SteamCMD. Into zombie-survival servers? Supercraft also hosts a managed Project Zomboid server hosting plan that stays persistent and online 24/7, automating installation, updates, and backups for you.

Prerequisites

  • OS: Ubuntu 20.04/22.04 LTS or Debian 11/12.
  • RAM: 8GB Minimum, 16GB Recommended.
  • Storage: 25GB+ Disk Space.
  • Dependencies: lib32gcc1 and steamcmd.

1. Install Dependencies

sudo apt update sudo apt install lib32gcc-s1 curl wget

2. Install SteamCMD

mkdir ~/steamcmd cd ~/steamcmd curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz" | tar zxvf -

3. Download DayZ Server Files

Run the following command to download the server (App ID: 223350):

./steamcmd.sh +force_install_dir ~/dayzserver +login anonymous +app_update 223350 validate +quit

4. Configuration (serverDZ.cfg)

Navigate to ~/dayzserver and create/edit serverDZ.cfg.

Key Settings:

  • hostname = "My DayZ Server";
  • password = ""; (Leave empty for public)
  • maxPlayers = 60;
  • steamQueryPort = 27016;

5. BattlEye Configuration

Go to ~/dayzserver/battleye/ and copy beserver_x64.cfg. Set your RCon password inside this file to enable remote administration.

6. Launching the Server

Create a startup script start.sh:

#!/bin/bash ./DayZServer_x64 -config=serverDZ.cfg -port=2302 -BEpath=battleye -profiles=profiles -dologs -adminlog -netlog -freezecheck

Make it executable: chmod +x start.sh and run it: ./start.sh.

Network Ports

Open the following UDP ports:

  • 2302 (Game Port)
  • 27016 (Steam Query Port)
  • 2303-2305 (Master Server & RCon)

Looking for a server we can host?

We don't run DayZ servers, but Project Zomboid is the closest game on Supercraft. Instant setup, 5 datacenter regions, no contract.
